數據以表格的形式

我有一個XML數據，我試圖把它轉換成普通表格式：數據以表格的形式

<html> 
    <head> 
    <title>report</title> 
    <model> 
     <instance> 
     <uploaded_form_dc8u7x id="reportform"> 
      <formhub> 
      <uuid/> 
      </formhub> 
      <household_number/> 
      <Survey_Name/> 
      <photo/> 
      <city/> 
      <date/> 
      <survey/> 
      <start/> 
      <end/> 
      <meta> 
      <instanceID/> 
      </meta> 
     </uploaded_form_dc8u7x> 
     </instance> 
     <bind constraint=" /uploaded_form_dc8u7x/household_number &gt;= 2" nodeset="/uploaded_form_dc8u7x/household_number" required="true()" type="int"/> 
     <bind nodeset="/uploaded_form_dc8u7x/Survey_Name" relevant=" /uploaded_form_dc8u7x/household_number &gt; 02" required="true()" type="string"/> 
     <bind nodeset="/uploaded_form_dc8u7x/photo" required="true()" type="binary"/> 
     <bind nodeset="/uploaded_form_dc8u7x/city" required="true()" type="select"/> 
     <bind nodeset="/uploaded_form_dc8u7x/date" required="true()" type="dateTime"/> 
     <bind nodeset="/uploaded_form_dc8u7x/survey" required="true()" type="select1"/> 
     <bind preload="timestamp" preloadParams="start" nodeset="/uploaded_form_dc8u7x/start" type="dateTime"/> 
     <bind preload="timestamp" preloadParams="end" nodeset="/uploaded_form_dc8u7x/end" type="dateTime"/> 
     <bind calculate="concat('uuid:', uuid())" nodeset="/uploaded_form_dc8u7x/meta/instanceID" readonly="true()" type="string"/> 
     <bind calculate="'05ef936fe45e41d1bc08474399d64191'" nodeset="/uploaded_form_dc8u7x/formhub/uuid" type="string"/> 
    </model> 
    </head> 
    <body> 
    <input ref="/uploaded_form_dc8u7x/household_number"> 
     <label>Household Number</label> 
    </input> 
    <input ref="/uploaded_form_dc8u7x/Survey_Name"> 
     <label>Survey Name</label> 
    </input> 
    <upload mediatype="image/*" ref="/uploaded_form_dc8u7x/photo"> 
     <label>photo</label> 
    </upload> 
    <select ref="/uploaded_form_dc8u7x/city"> 
     <label>city</label> 
     <item> 
     <label>pune</label> 
     <value>pune01</value> 
     </item> 
     <item> 
     <label>mumbai</label> 
     <value>mumbai02</value> 
     </item> 
     <item> 
     <label>ahmednagar</label> 
     <value>ahmednagar03</value> 
     </item> 
     <item> 
     <label>delhi</label> 
     <value>delhi04</value> 
     </item> 
    </select> 
    <input ref="/uploaded_form_dc8u7x/date"> 
     <label>date</label> 
    </input> 
    <select1 ref="/uploaded_form_dc8u7x/survey"> 
     <label>survey</label> 
     <item> 
     <label>xyz</label> 
     <value>xyz1</value> 
     </item> 
     <item> 
     <label>abc</label> 
     <value>abc1</value> 
     </item> 
    </select1> 
    </body> 
</html>

我試圖讓表的形式的數據：

city   survey 

    Pune   abc 

    mumbai   xyz 

    ahmednagar 

    delhi

任何人都可以幫我解決這個問題嗎？

什麼應該是選擇查詢來實現這一目標？

我想通過postgresSQL選擇表格格式的數據。我想把「城市」和「調查」作爲單獨的列，並提及其數據。

我曾嘗試以下查詢：

SELECT xpath('/html/body/input/label/text()', xml_content) as house_number from logger_xform;

它給我一個行，而不是單獨列的結果：

「{ABC，XYZ}」，「{浦那，孟買，阿邁德那格爾，德里}」
